Description
Details
The most common configuration for the CMUcam4 is to have it communicate to a master processor via a standard TTL serial port. This “master processor” could be a computer (through USB or RS232), Arduino, Basic Stamp, PIC, or similar microcontroller. The CMUcam4 is small enough to add simple vision to embedded systems that can not afford the size or power of a standard computer based vision system. Its communication protocol and baud rate is designed to accommodate even the slowest of processors. For even slower processors, the CMUcam4 can operate in “poll mode”. In this mode, the host processor can ask the CMUcam4 for just a single packet of data. This gives slower processors the ability to more easily stay synchronized with the data. It is also possible to add a delay between individual serial data characters using the “delay mode” command. Due to communication delays, both poll mode and delay mode will lower the total number of frames that can be processed in one second.
The RCA and barrel jack aren't populated because the connectors can affect the field of view when mounting the unit in an enclosure. Also, the servo power bus is disconnected in its default state, you will need to close the 'Servo EN' jumper on the back side of the board to enable power to the Pan/Tilt servos.
To program the Arduino with the CMUcam shield connected, you need to either use the 'HALT' feature, or disconnect the serial jumpers (SJ4 and SJ5), connect the two pin header (J1) to any digital Arduino pins, and then use the SoftwareSerial library included in the Arduino installation.
